Answer 1

Answer:

D y = 9/x

Step-by-step explanation:

An inverse variation is of the form

xy = k where k is a constant

We can write this as

y = k/x

The only equation that is of this form is

D y = 9/x

Answer 2

Answer:

$\boxed{\mathrm{Option \: D}}$

Step-by-step explanation:

Inverse variation is written as:

$y=\frac{k}{x}$

Where k is the constant of proportionality.
